Abstract: The invention relates to a device for covering and sealing a hole (10) through a wall provided for leading cables therethrough, said hole being provided in, for example, a switchgear cabinet. The device comprises a retaining frame (16), which can be fastened to the edge (66) of the hole through the wall (12), and comprises a number of bushes (30, 31), which are made of elastomeric material, can be removeably inserted inside frame openings (28), and which can be fixed therein. A least one part of the bushes (30, 31) is provided with at least one through opening for a cable. In order to equip the cable leadthrough with cables in a particularly easy manner and to be able to mount it on the switchgear cabinet, the invention provides that the frame openings (28) are open on one side for inserting the bushes (30, 31). In addition, one of the bushes (31), which can be inserted into the frame openings, can be arrested in a direction of insertion in the area of the sidewalls (36) that delimit the frame openings (34).
